Why is the thread breaking on my DURKOPP ADLER Sewing Machine?
- A
  Ashley PatelAug 8, 2025
  Thread breakage in your DURKOPP ADLER Sewing Machine can occur due to several reasons: the needle thread and looper thread might not be threaded correctly, the needle could be bent or sharp-edged, or it might not be inserted correctly into the needle bar. The thread used may be unsuitable, or the thread tensions might be too tight for the thread. Also, check if thread-guiding parts are sharp-edged and whether the throat plate, looper, or spread have been damaged by the needle. To resolve this, check the threading path, replace the needle if necessary, ensure correct needle insertion, use the recommended thread, and check thread tensions. If parts are damaged, have them reworked by qualified specialists.

  Thread breakage in your DURKOPP ADLER Sewing Machine can occur for several reasons. The needle thread and hook thread might not be threaded correctly, so check the threading path. The needle could be bent or sharp-edged, in which case you should replace it. Ensure the needle is correctly inserted into the needle bar. The thread used might be unsuitable, so switch to a recommended thread. Also, thread tensions might be too tight for the thread being used, so check them. Sharp-edged thread-guiding parts, such as the thread tube, thread guide, or thread take-up disk, can also cause breakage, so check the threading path. Finally, the throat plate, hook, or spread may have been damaged by the needle, requiring rework by qualified specialists.
